DVRS Installation & Programming Guide – PART II

Dispatcher Initiated Remote DVRS Activation

Dispatcher can send a Call Alert (Page) to a specific MSU, which in turn causes DVR
mode change in the following order: OFF-SYS-LOC-OFF.
If remote mode change is enabled in the MSU then the Call Alert Page feature must be
made available to the Dispatcher only. The rest of the System subscriber equipment
must not have the Call Alert (Page) feature enabled since paging a specific MSU
interfaced to a DVR will toggle the DVR mode and may cause loss of vital
communications.
To enable the DVRS Remote mode change in the MSU and only allow the Dispatcher to
use Call Alert functionality, the 'System Remote Activation / Deactivation' box in the
Radio Wide  VRS/DVRS Tab must be checked.
It is recommended that remote mode change is disabled in the MSU and enabled
in the DVR as described below.
To disable the DVRS Remote mode change in the MSU and enable this functionality in
the DVR, the 'System Remote Activation / Deactivation' box in the Radio Wide 
VRS/DVRS Tab must be unchecked and the DVR must be programmed with the ID of
the dispatcher console in its VR Activation ID Data table. In this case only Pages from
this specific ID (or IDs) will cause DVRS mode change.
In addition, the DVRS may send back a mode change status to indicate its current mode
(OFF, SYSTEM, LOCAL). Only the Dispatcher Console can interpret those status
messages if correctly programmed:
Status 1 = OFF mode
Status 2 = LOCAL mode
Status 3 = SYSTEM
The MSU also must be programmed to send Status 1, 2 and 3.
IMPORTANT: The MSU should have only one System Unit ID programmed for all
DVRS Enabled Systems. If the MSU is programmed with different Unit IDs in different
Systems, then Call Alert Page may cause intermittent and unreliable DVRS mode
change.

P25 Trunking OTAR via DVRS

If the PSU users require the P25 Trunking OTAR feature to work via DVRS, the MSU
must have the 'Packet Data Capable System (PDS)' Option enabled in the
corresponding Trunking System N  Data screens.

SCAN ON/OFF

To suspend MSU Scan when DVR is ON (recommended):
Scan  Scan Configuration  check "Suspend Scan on DVRS Active"
When the MSU is programmed (recommended) to suspend SCAN when DVR is ON, the
following SCAN scenarios are available:
